Abstract:

The metal-functionalized 1,3-diphospha-2-propanone I reacted with 2 equiv Me2S(O)CH2 to give the 1,5-diphospha-3-pentanone complex II, which was subjected to x-ray anal. Reaction of I with Ph3PCH2 gave phosphorus ylide III, which was examd. by IR, mass, and 1H, 13C, and 31P NMR spectroscopy.
